What is Virtual Environment?

An isolated Python environment that maintains its own set of packages, independent of the system Python installation.

Virtual environments solve dependency conflicts between projects. Each environment has its own Python binary and package directory. Created with python -m venv or virtualenv, they ensure project A can use Django 3.2 while project B uses Django 4.1.

Activate with source venv/bin/activate (Linux/Mac) or venv\Scripts\activate (Windows). pip freeze > requirements.txt captures dependencies for reproducibility.
